How can I catch a error in a BAPI?

Question

Hi,
I use BAPI L_TO_CREATE_MULTIPLE. If, for example, I put a warehouse that not is the warehouse of the unit that I want to move, I receive an error that isn't in exceptions.
In the program, I need, in the sy-subrc, catch this error, to do anything.
In this case, the message is L3208.
Thank you very much.

Hello Jose
BAPIs must not raise any exceptions. Why? Because they are intended for external use. However, if you raise an exception during a RFC call the connection will break down. Therefore BAPIs collect the error message in their (usually named) RETURN parameter.
In order to evaluate a BAPI call you can simply code like this:
" Assumption: RETURN parameter is an itab of type BAPIRET2
LOOP AT return TRANSPORTING NO FIELDS
          WHERE ( type CA 'AEX' ).
  EXIT.
ENDLOOP.
IF ( syst-subrc = 0 ).
" A(bort), E(rror) or X(dump) happened
ENDIF.
